LEON FOREST DOUGLASS, OF GRAND ISLAND, NEBRASKA ,AUTDMATIC COIN-CONTROLLED PHONOGRAPH.

SPECIFICATION forming part of Letters Patent No. 431,883, dated July 8, 1890 Application filed April 16, 1890- erial No. 348,169. (No model.)

To aZZ whom it may concern: I

Be it known that 1, Leon Fonnsr Douc- LASS, a citizen of the United States, residing at Grand Island, in the county of Hall and State of Nebraska, have invented certain new and useful Improvements in Automatic Ooin- )ontrolled Phonograph Service; and I hereby declare the following to be a full, clear, and

exact description thereof, reference being had to the accompanying drawings, wherein Figure 1 is a rear elevation of devices embodying myinvention, one side of the case removed, and also so much of a phonograph as is necessary to show the operation of the devices. Fig. 2 is a front elevation of the same, showing the releasing mechanism. Fig. is an enlarged view of the make and break devices and diagram of circuits.

Like symbols refer to like parts wherever they occur.

My present invention relates to the 0011- struction of coin-controlled mechanism employed for purposes of trade, and, while in part generally useful for all classes of vending apparatus when combined therewith, it has as a whole been especially devised for phonograph service, and therefore is illustrated in connection therewith, disclaiming any limitation thereto, except where so specifically stated in the claims.

lnsomuch as the devices en'ibracing my invention may be combined and connected with any phonograph, and as the construction and operation of phonographs are well understood in the art, the phonograph is not herein described, and only such parts thereof as are connected with my devices are specifically named. Furthermore, though a motor for operating the phonograph is employed, the particular construction thereof is not material, and therefore the motor has only been indicated by dotted lines.

One object I have in view is to simplify and render efficient the make-and-break devices which control a circuit wherein is an electric motor, said circuit being closed by levers to release the coin and thus break the circuit, which combination embraces the first feature of my invention.

The second obj ectI have in view, and which applies more especially to those cases where a phonograph or like mechanism is controlled by the circuit, is to provide a carriag e-releasing mechanism for releasing the carriage from the power at the end of its traverse, and to this end I combine with the circuit which operates the motor and its make-and-brcak devices a second set of make and-break-devices nograph; O, the shaft of the motor, and D a governor therefor.

E indicates my improved malze-and-brake mechanism, which is to be operated by inserting a coin through a slot in the case, (not shown,) is now commonly practiced in automatic vending apparatus or slot-machines.

In the drawings, Fig. 1, the case has been removed to disclose the metallic supportplate 6. On the metallic plate e are pivoted two arms or levers 1 and 2, preferably elbowlevers, pivoted at the angle arranged to-form the sides of a coin-chute, said levers being either weighted or held in position by springs 3 4, as preferred. In rear of the arm or lever 1 is an insulated post 5, provided with a contact-point 6, from which a wire 7 leads to the motor, the circuit being completed by way of metallic plate 0 and wire 8 through the battery which operates the motor. The opposite pivoted lever or arm 2 projects beyond the case and stands in the path of a weight 19 or equivalent device, for purposes which will in equivalent manner-together with an insulated post 13, contact-point 14-, from which a wire 15 leads to an electro-magnet 16 and thence to the battery, the circuit being completed by metallic plate e and wire 8, the same as in the case of the make-and-break mechanism which controls the motor. A limiting post and screw 17 is provided to control the vibration of lever 10, and a pivoted lever or arm 18, one end of which stands in the path of weight 19, is provided to retract the pivoted lever and allow the escape of the coin when the weight 19 in its descent strikes the arm of lever 18.

a indicates the diaphragm-carriage of the phonograph A. To said carriage is attached one end of a cord 20, which passes overa series of rollers or pulleys 21 22, and is provided at its other end with a weight 19, arranged to rise and fall at the side of the case of the make-and-break mechanism before described, so as to strike alternately the projecting arms 2 and 18, and thus vibrate the levers 2 and 10. This weight 19 is raised when the diaphragm-carriage a is moved forward by the motor and usual feed-screw mechanism and serves to retract the carriage when released.

In order to release the carriage a, the usual releasing mechanism thereof is connected with the armature 16 of the electro-magnet 16 (arranged in the second circuit) by means of a chain or cord 16 or in any equivalent manner, so that when the circuit 14 15 c 8 is made the armature 16 will be drawn down, the diaphragm-carriage Ct will be raised to release it from the feed mechanism of the phonograph, and the weight 19 will operate to retract the carriage to its first position.

The devices being constructed substantially as hereinbefore specified will operate as follows: A nickel or other suitable coin or token is dropped through a slot in a suitable casing inclosing the make-and-break mechanism, which coin falling in the chute between the pivoted arms 1 2 forces them apart until arm 1 comes in contact with contact-point (5, closing the circuit through post 5, wire 7, and metallic plate a and wire 8 to the, battery and motor. The motor is thus set in motion and feeds the phonograph-carriage a (by means of the usual mechanism) on the plate 6 and held by springs 11 12, or

to the end of its travel, which movement of the carriage lifts the weight 19 until it strikes the arm 2 of pivoted lever 2, retracting said lever and releasing the coin, which also releases pivoted lever 1 and breaks the circuit to the motor. The coin on escaping from pivoted levers 1 and 2 descends between pivoted levers 9 and 10, forcing them apart and bringing lever 9 in contact with contactpoint let, thus completing the second circuit through post 13, wire 15, the electro-magnet 16, battery, wire 8, and metallic plate 6. This energizes the electro-magnet 16, which attracts the armature 16, and thus actuates the carriage-releasing mechanism, whereupon the weight 19 by its descent retracts the carriage, and at the lower point of its descent said weight strikes the pivoted lever 18, cansing the same to retract the pivoted arm 10 and release the coin, thus breaking the second circuit and restoring the devices to their first condition ready to be again operated by the introduction of another coin.

Among the advantages of my devices are extreme simplicity of construction, effectiveness for the purposes intended, and non-lia bility to get outof order.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination, with a phonograph and its motor, of a circuit, a circuit-breaker arranged in a coin-chute and adapted to hold a coin or token, and means for actuating the circuit-breaker from the phonograph-carriage to release the coin, substantially as and for the purposes specified.

2. The combination, with a phonograph and its motor, of two circuit breakers arranged in a coin-chute and two circuits, the first of which includes the motor and the second includes an elect-ro-magnet, and a carriage-release actuated by the electro-magnet of the second circuit, substantially as and for the purposes specified.

3. The combination of two pivoted levers arranged in a coin-chute, a contact-point arranged in rear of one of said pivoted levers, a circuit, a motor, and means for tripping the other of said pivoted levers, substantially as and for the purposes specified.

1. The combination of two pairs of pivoted levers arranged one above the other in a coinchute, a contact-point arranged back of one lever of each pair, a trip mechanism for the other lever of each pair, a circuit from the first pair which includes a motor, and a circuit from the second pair which includes an electro-magnet, substantially as and for the purposes specified.

In testimony whereof I affix my signature, in presence of two witnesses, this 9th dayof April,

LEON FOREST DOUGLASS. \Vitnesses:
